UC Davis electrical engineers have created a chip-sized device to measure the spectrum of visible and infrared light. The spectrometer-on-a-chip could have a wide range of applications in medicine, ...

This is a close-up view of the “spectrometer-on-a-chip” technology that could dramatically reduce the size of spectrometers in the future. (Credit: NASA Goddard/Chris Gunn) The Composite Infrared ...

Red laser light is coupled into a spectrometer chip with an optical fiber from the left. The light travels along the chip until it is scattered out the the top in a waveguide section on the right.

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory ...

Resting on a fingertip, this miniature sensor replaces bulky laboratory equipment by using photon-trapping surface nanostructures and artificial intelligence (AI) to accurately analyze disease, check ...

SNSPDs have been widely used in various applications requiring single photon detection thanks to their attractive performances. Since SNSPDs are thin films of serval nanometers in thickness, they are ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
